Flushing system for a commode



9 1951 c:. B. WIGGS FLUSHING SYSTEM FOR A COMMODE Filed Aug. 22, 1960 INVENTOR 35 CHAR .55 W/ cos ATTORNEY 3,010,115 FLUSHING SYSTEM FOR A COMMODE Charles B. Wiggs, 22 N. Ellis St., Cape Girardeau, M0. Filed Aug. 22, 1960, Ser. No. 51,120 3 Claims. (Cl. 4-69) This invention relates to a novel flushing system for a bathroom commode, and more particularly to a flushing system which eliminates the conventional water storage tank and the conventional mechanism normally associated therewith and contained therein to elfect flushing of the water closet.

Another object of the invention is to provide a flushing system of extremely simple construction which may be very economically manufactured and installed and which will require substantially no servicing, due to the fact that the system eliminates all of the conventional mechanism associated with the storage tank of a water closet.

Still another object of the invention is to provide a flushing system which will eliminate leakage and which will substantially eliminate noise commonly occurring in effecting the flushing of a water closet.

Various other objects and advantages of the invention will hereinafter become more fully apparent from the following description of the drawing, illustrating a present ly preferred embodiment thereof, and wherein:

FIGURE 1 is a side elevational view of the flushing system shown connected to a conventional commode, illustrated in section;

FIGURE 2 is an enlarged fragmentary plan view, partly in horizontal section, of a part of the flushing system, and

FIGURE 3 is a fragmentary vertical sectional view, on an enlarged scale, taken substantially along a plane as indicated by the line 33 of FIGURE 1.

Referring more specifically to the drawing, the flushing system in its entirety and comprising the invention is designated generally 5 and includes a pipeline, designated generally 6, including pipes 7 and 8 connected by an elbow 9. A pipe 10 of the pipeline 6 is connected to the pipe -8 by a T-coupling 11 and a pipe 12 is connected to the pipe 10 by an elbow 13. The pipe 7 has a threaded end 14 constituting the inlet end of the flushing system 5 and the pipeline 6 and the pipe 12 has a threaded end 15 constituting the outlet end of said pipeline 6.

The threaded end 14 is connected to one end of a conventional valve 16 and the opposite end of said valve is connected to the discharge end of a conduit 17 leading from a source of water supply under pressure for connect ing the flushing system to the water supply source. The discharge end 15 is secured in the inlet end of a passage 18 of a conventional commode or water closet hopper 19, the other end of which communicates with the inner end of the hook-shaped trap passage 20 of the commode. The other, downwardly opening outlet end 21 of the trap passage 20 connects in any conventional manner with a pipe 22 leading to a sewer.

The flushing system 5 also includes a branch passage, designated generally 23, having a pipe 24 connected to the T-coupling 11 and to the enlarged end of a reducer coupling, the smaller end of which coupling 25 is connected to one end of a pipe 26. An elbow 27 connects the other end of the pipe 26 to one end of a pipe 28. The other end of the pipe 28 is connected to an inlet fitting 29 provided in the top of a tank 30, and a pipe 31 connects to an outlet fitting 32 in the bottom of the tank and is connected to a pipe 33 by an elbow 34. The other end of the pipe 33 is connected to a ring shaped pipe 35 by a second T-coupling 36.

States Q 3,010,115 Patented Nov. 28, 1961 The pipe 33 extends through an opening 37 of the commode 19, which is located above the inlet end of the passage 18 and immediately beneath the rim 38 of the commode. The coupling 36 is located within the top part of the bowl 39 of the commode and supports the ring-shaped pipe 35 within the upper part of the bowl and beneath the rim 38. The pipe 35 has longitudinally or circumferentially spaced inwardly opening apertures 40, as best seen in FIGURES 2 and 3. A restricted open lower end 41 of the bowl 39 opens into the junction of the passages 18 and 20.

The valve 16 is of a conventional normally closed type having an actuating handle 44. To flush the commode 19, the handle 44 is swung downwardlyto open the valve 16 to allow water under pressure to pass through said valve and into the pipe 7. The water under pressure will flow unimpeded through the pipeline 6 and discharge into the upper inlet .end of the downwardly inclined commode passage .18 to elfect flushing of the contents of the commode 19 through the trap passage 20. At the same time, a part of the water entering the coupling 11 will flow through the branch passage 23. However, this flow to the tank 30 will be restricted by the reducer coupling 25 and by the pipes 26 and 28 and coupling 27, the bores of which are of smaller diameter than the bores of the pipes 10 and 12 and coupling 13. The water entering the tank 30 through its inlet 29 will flow by gravity therefrom through its outlet 32, pipe 31, coupling 34, pipe 33, coupling 36 and into both ends of the pipe 35. The water entering the pipe 35 will be discharged into the bowl 39 through the apertures 40. However, the apertures 40 will restrict the escape of water from the pipe 35 so that the tank 30 will become filled or partially filled before the valve 16 automatically resumes a closed position for shutting off the flow of water to the flushing system 5, and which will occur after the contents of the commode 19 has been flushed through the outlet end 21 of the trap passage 20. Thereafter, the water within the tank 30 will flow by gravity to the pipe 35 and discharge through the apertures 40 for refilling the bowl 39 to the level 42, corresponding to the level of the topmost portion of the trap wall 43. A sufiicient quantity of water will collect in the tank 30 each time that the valve 16 is opened to insure refilling of the bowl 39 up to the normal water line 42.

It will thus be seen that a flushing system of extremely simple construction has been provided containing no moving parts other than the conventional manually actuated normally closed valve 16 and thus involving no parts which will require replacement, under ordinary conditions. Further, so long as the valve 16 does not leak no leakage can occur in the flushing system 5, and as said system contains no moving parts the souds normally occurring in connection with the flushing of a conventional water closet, due to its moving parts, are eliminated.

Various modifications and changes are contemplated and may be resorted to, without departing from the function or scope of the invention as hereinafter defined by the appended claims.

I claim as my invention:

1. A commode flushing system comprising'a pipeline adapted to be connected to a source of water supply under pressure and having an outlet adapted to discharge directly into a flushing passage of a commode for flushing the commode when water is supplied under pressure through said pipeline, and a branch passage forming a part of the flushing system having one end connected to said pipeline above the level of the commode and an opposite discharge end adapted to open into the commode, a tank interposed in said branch passage and disposed above the level of the commode and adapted to be filled during stricting the flow of water to the tank.
